“Age of Apocalypse” is a 1995–1996 comic book crossover story line published in the X-Men franchise of books by Marvel Comics.
The ’90s were all about crazy events, changing continuity around and altering characters in unexpected ways. It started with the “Death of Superman,” continued into Spider-Man’s “Clone Saga,” and hit the X-Men in the form of “Age of Apocalypse.” It starts, like many comic events do, with completely botched time travel. A mutant named Legion, the son of Professor Charles Xavier, goes back in time to kill Magneto but ends up killing his father instead. With Professor X dead, Apocalypse shows up and pretty much wrecks the world to make a post-apocalyptic (pun intended) future.
Cyclops is missing an eye, Wolverine has lost a hand and all the good guys are following Magneto in a resistance movement against Apocalypse’s bloody, iron-fist rule of mutants over humans. The new future replaced all the X-Books during its run and quickly became a fan favorite. The event wrapped up with the group sending Bishop back in time to save Professor X, thus restoring the timeline.
